Two kinds of aftermarket cigarette lighters are available, those with an illumination bulb (A) and those without (B). Many useful accessories simply plug into the lighter socket. Vacuum cleaner (C), under-bonnet inspection light (D), dash-mounted cooling fan (E) and map reading light (F) can all be used in this way.
